ABSTRACT: The life history of Epicarnpoptera andersoni glauca Hmps. on robusta coffee, Coffea canephora Pierre ex. Froehner. was investigated in the laboratory at 27±2°C and 70-80% RH. Larvae moulted four or five times irrespective of the sex. Development from egg to adult was completed in an average of 26.3 days when larvae passed through five instars and in 31.7 days when larvae passed through six instars. The mean growth ratio, determined from head capsule measurements, was 1.44. The sixth instar larva was the most voracious in feeding, consuming 86.45% of the leaf area offered per day.
